Qiagen Qiaquick vs MinElute PCR purification kit for ChIP DNA

I am using using the Qiagen cleanup kits to purify DNA samples from ChIP (in the range of ng) for qPCR. However I'm not sure which of the following would be best for maximising the yield of a small amount of ChIP DNA:

1. Qiaquick and elute in 30 ul
2. MinElute and elute in 10 ul, then dilute to 30 ul

Both the Qiaquick and MinElute kits state the same predicted yields at ~80%. The protocols for the kits discuss the upper binding capacity of the columns, but not the loss at lower DNA amounts. I need more than the 10 ul elution volume of the MinElute kit, as I will need to perform several qPCR reactions from each DNA sample.
